Metapost: Moving pictures

A new post in imminent but in the meantime I've added a few YouTube links to the existing entries. Ironically enough, I've had some difficulties with Blogger's editing software while trying to do this - hey Google, it's your product I'm plugging - and I have to extend my apologies to the Undertones, who I don't think ever made a video for the song I chose, McAlmont, who seems too obscure and Squeeze and the Supernaturals whose names produce too many false positives.
